Materials and methods

Test guideline
Qualifier:
according to guideline
Guideline:
OECD Guideline 405 (Acute Eye Irritation / Corrosion)
Principles of method if other than guideline:
100 µl test compound was instilled into the conjunctival sac of one eye of each of 3 rabbits. The lids were then gently held together for about one second. the other eye remained untreated and served as control. The treated eye was washed out with physiological NaCl solution 24 hours after instillation of the test compound
GLP compliance:

Any other information on results incl. tables

The test substance was slight to moderately irritating to the eye. According Directive 67/548 EEC a classification is not required - however according GHS a classification a Eye Irrit.2; H319 is justified based on a cornea score > 1and a conjunctiva score > 2.
